Lower Thalamic Blood Flow Is Associated With Slower Stride Velocity in Older Adults

BackgroundGait deficits are associated with brain atrophy and white matter hyperintensities (WMH) – both markers of underlying cerebral small vessel disease (SVD). Given reduced subcortical cerebral blood flow (CBF) is prevalent in SVD, we tested the hypothesis that regional CBF is positively associated with gait performance among older adults.MethodsThirty-two older adults (55–80 years) with at […]

Adding Types, But Not Tokens, Affects Property Induction

Abstract The extent to which we generalize a novel property from a sample of familiar instances to novel instances depends on the sample composition. Previous property induction experiments have only used samples consisting of novel types (unique entities). Because real‐world evidence samples often contain redundant tokens (repetitions of the same entity), we studied the effects […]

Evaluating Models of Gesture and Speech Production for People With Aphasia

Abstract People with aphasia use gestures not only to communicate relevant content but also to compensate for their verbal limitations. The Sketch Model (De Ruiter, 2000) assumes a flexible relationship between gesture and speech with the possibility of a compensatory use of the two modalities. In the successor of the Sketch Model, the AR‐Sketch Model […]
